FLY-ESCAPE.

'fipccifloation of Letters I'atent. Patented A 23,.1918

Application filed July is, 1917. Serial No. 180,437.

To. all whom it may concern:

l 3e it known that I, VIOLA D. Muzzy, a. citizen of the United States, residing at Spartansburg, in the county of Crawford and State of Pennsylvania, have invented new and. useful Improvements in Fly- Esc'apes, of which the following is a 'epecikh cation. 7

This invention relates to window screens, and more especially to exits through which files and other insects are permitted to escape frorn the apartment protected by the screen; and the object of the same is to rom-a n fly escape of this charm ctcr applicnhle to the screens in windows'or doors or to the glues panes therein, and in this respect I reserve thebroadest use of the. invention.

The present invention is an escape which isnmde of transparent material so that it the passage of light and which has an up *crdlyfldeficctcd nozzle or iii ple and a body of such fo1'n1ation that it is'directed toward the same.

Tlu'oughout the following specification" I ref'rto the attachment of an escape to a Window screen, but at one point in the drawlogs the escape is shown as n iplicd to 1 window sash, and I wish it to be distinctly understood that my invention is n 'splicnlile to either kind of sash or to the frame of a door at its corner, whetherthe transparent sheet of said door is of or screening. .111 other words, whatever the language hereinafter employed, it is my intention that this invention shall he applied to the. frame of it screen, a. sash, or a. door. On this understanding I have used the letter-F to designate the frame, and S and G to designate respectively the screen wire or the glass panc. Furthermore, while not specificall illustrated in the, drawings, it. is possible that my escape could be attached to the frame Fof a structure whose body was not transparent or translucent, or in other wordscn ordinary door. In that case one corner of the panel would be cut out just inside the frame for the insertion of the escape itself as; described below, and as the escape is of glass or other transparent material, it admits its own light and attracts the flies on the interior of the builoing.

Details are set forth in' the following specification, reference being had to e accompanying drawings wherein F lgure jl is El, perspective iew of one co'rner of a window screen provided with my improved escape, looking at the, same from the inside of the screen, and thisw'iew includes a detail of the other upper corner of the screen as it is cut before the escape is attached thereto,

Fig. 2 is an enlarged detail of the escape for use on a screen, and Fig. 3 is a sectional detail of the escape and screen.

Fig. 4: is a vertical section of a window sash frame, taken through one of these escapes which has been molded in its corner.

The escape is of glass or similar translucent material. It comprises a body 1 formed in the shape of a. right-angular triangle, and inoldedns part of and projecting from theplane of the bodyat itscenter ,is n tubular nipple 2 constituting nnozzle whose inlet end 3 where it unites with the plate is larger than its outlet end. or month 4 and whose body preferably inclines slightly upnurd from its inlet to its outlet end when 7 the plate is in place. When the escape is to he applied to a screen its plate ha a row of perforations 5 along the hypotenuse of ihe triangle as seen in Fig. 2, and these perforations may be carried along its other two side-i as seen at 6, and a lacing Wire 7 is p; i'iir'ough all perforations and the inceh of the swoon. The latter may hecut. out near a corner with a triangular opening, as eecn at the left f Fig. 1, leaving a littleof the screen remaining adjacent the contignous sides of the ironic at itc corner, and the raw edges of the screen Wire are turned hack all around the openings; and then when the lacing; is applied it passes through the i'hesh of the screen all around the opening. By preference I use copper wire for the lacing, and it should be rather fine so that it will he hardly noticed. I might say that it is possible to insert the right-angular edges of the plate 1 under the heading which holds the screen in the frame, and hold such edges in that manner Without the lacing along them, but in any event the lacing Will be carried along the hypotenuse and the other edges will engage closely beneath or at least against the frame or its beading so that the triangular escape fits close in the corner of 'ihe frame.

The escape when intended for application to the pane G of a window sash will bemade in the same manner excepting that allperforntions will be omitted. Along its hy otenuse it may then have a groove or ra bet 10 to engage over the edge of the glass G body of the plate line, and its right-angular edges will be inserted in the rabbet ofthe frame-the putty being removed for this purpose and i replaced and painted so that the escape is hardly noticeable from either the exterior or the interior.

When now one or more of these escapes are applied to a sash, flies on the interior of the building who usually fly toward and light upon the screen or glass in the forenoon or'at other times of day when it is bright out of doors, crawl up the surface thereof and onto the escape, pass into its larger inner end and along its body, and fly out its outlet end 4, and away; and later, especially toward evening when I have observed that they return and seek to reenter the house, they light on the outer face of the screen or glass but will not find their way into the restricted months 4 of these escapes, and therefore, they are trapped outside the dwelling. The presence of one or more of these escapes in the'corners of a sash will hardly be noticed and will not interrupt the admission of light to a perceptible degree; and if they are applied to the glass --(J" of a window sash, they admit practically no cold through their openings, even in the severest weather. Care should be taken that the nozzles or nipples do not project so far beyond the screen or glass of a lower sash that they will strike-the lower rail of the upper sash when said lower sash is raised or when said upper'sash is lowered; but if the 1 is overlaid on the inner side of the sash or screen, the nozzle or nipple may project through the opening cut away therein and for some little distance,

without protruding beyond the plane of the 40 outer side of the sash.

Whatis claimed as new is:--

1. In a fly escape, the combination'with a frame,'and a sheet therein cut away on an oblique line at one corner of the frame; of a triangular transparent plate seated in said corner with its right-angular edges engaging the frame and its h potenuse overlyin said oblique line, the p ate being provid with a tubular nozzle having a larger inner end opening through the plate and its body inclined upward and outward to a reduced mouth at the outside of the frame, and means for holding theplate in place.

2. In a fly escape, the combination with a lra|ne,'and a screen therein cut aw ay'at one corner; of a triangular transparent plate seated in said corner with its hypotenuse overlapping the screeen and perforatet, a fastening device threaded through the perforations and the screen, and a tubular nozzle carried by the plate and projecting outward of the screen, for the purpose set forth. 3. In a fly escape, the combination with the'frame, and a screen therein cut at one corner with a triangular opening and the edges of the screen wire turned back around the three sides of said opening; of a triangular transparent plate seated in said corner and having two edges engaging the frame and its hypotenuse overlappin thescreen and all edges perforated, a tuhula r nozzle carried by the plate and projecting outward of the frame, an a wire laced through the perforations an the screen rnesh.

In testimony whereof I afiix my signature;

VIOLA D. MUZZY.
